You will find the answers immediately after each question.Passage:In an age where technology seems to be taking over every aspect of our lives, there remains one activity that has not been overshadowed by digital advancements: reading traditional books. Despite the popularity of e-books andaudiobooks, many people still prefer the tactile experience of holding a physical book and turning its pages. This preference for traditional books is not only due to nostalgia but also because of the unique benefits they offer.A recent study conducted by the National Reading Agency found that individuals who read physical books tend to have a better memory of the content compared to those who read the same material on digital devices. Furthermore, there is a growing concern about the impact of screen time on sleep patterns, with research suggesting that reading from screens before bedtime can negatively affect the quality of sleep. Physical books, on the other hand, do not emit blue light which can disrupt melatonin production, thus helping readers get a good night’s rest.Moreover, libraries and bookstores continue to thrive as communal spaces where people gather to share ideas and engage in discussions about literature. The atmosphere in these places fosters a sense of community and a love for reading that cannot be replicated online. While digital media offers convenience and access to a vast amount of information, it does not replace the unique experience of visiting a library or bookstore.In conclusion, while technology offers many conveniences, the tradition of reading physical books remains strong. It provides a way to disconnect from the digital world, improve memory retention, and foster social connections within communities.End of PassageQuestions:1、According to the passage, what is one benefit of reading physical books over digital devices?Answer: Better memory retention of the content.2、What potential negative effect on health is associated with reading from screens before bedtime?Answer: Disruption of sleep quality due to blue light affecting melatonin production.3、How do libraries and bookstores contribute to community life according to the text?Answer: They serve as communal spaces where people gather to share ideas and engage in discussions about literature.4、What does the passage suggest about the future of physical books despite technological advances?Answer: Physical books will remain significant as they offer ways to disconnect, improve memory, and foster social connections.四、阅读第二节（12.5分）Title: The Art of MeditationReading Passage:Meditation has been a part of human culture for thousands of years, serving as a means for relaxation, stress reduction, and spiritual growth.

There is only one correct answer for each blank.Passage:The world of the internet has transformed our lives in countless ways. It has made information more accessible than ever before, connecting people across the globe in real-time. However, it also poses new challenges and risks. One of these is the increasing amount of misinformation that can be found online. While the internet is undoubtedly a valuable tool for learning and communication, it requires users to develop critical thinking skills to discern fact fromfiction. This ability is particularly important for young people who have grown up with easy access to technology but may lack the experience necessary to judge the 1 of the information they encounter.In addition to being able to evaluate the credibility of online content, digital literacy involves understanding the importance of privacy and security measures when using the web. Sharing personal details on social media platforms can make individuals vulnerable to identity theft and other forms of cybercrime. Therefore, it is essential to educate children about the risks associated with 2 too much personal information online.Another challenge of the digital age is the potential for addiction to electronic devices and the internet itself. The constant connectivity can lead to a feeling of being overwhelmed by the constant influx of 3. This is why many experts recommend setting boundaries around screen time and encouraging alternative activities that promote mental well-being.Despite these challenges, the internet remains a powerful force for good, providing opportunities for collaboration, innovation, and learning.

One effective method is to immerse yourself in the language by watching movies, listening to music, and reading books. This not only helps you get accustomed to the pronunciation and intonation but also exposes you to a wide range of vocabulary and expressions.However, it is important to note that simply listening and watching is not enough. You need to actively engage with the language by speaking and writing. Try to find a language exchange partner or join a conversation group to practice speaking. This will not only improve your speaking skills but also help you gain confidence in using the language in real-life situations.When it comes to writing, start by keeping a daily journal in the targetlanguage. This will help you practice your writing skills and keep track of your progress. Don’t worry if you make mistakes; they are an essential part of the learning process. The key is to be consistent and not be afraid to make mistakes.In conclusion, the key to mastering a new language is to find the right balance between memorization and practice. By immersing yourself in the language, actively engaging with it, and being patient and persistent, you will eventually achieve your goals.Grammar Completion:Choose the most appropriate word or phrase to complete the following sentences.

吉林省长春市朝阳区长春外国语学校2023-2024学年高三上学期11月期中英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读理解With the cost of living in the United States soaring, more and more people are setting their sights on an international destination.EcuadorFor real bargain hunters, Ecuador is cheap and safe with a very comfortable year-round climate. The cost of living for one person in the country is $750. Ecuador is geographically diverse with miles of endless beaches, hills and rainforests. Housing is economical with the average rent for one person costing around $307 per month.Costa RicaCosta Rica is the perfect place to live abroad without depleting(耗尽)your savings. The cost of living is around $893 and rent for one person runs approximately $406 per month. The tropical destination has cost-effective healthcare. The weather is gorgeous, the water is warm and the housing is highly affordable.UruguayThe country is exquisite(精美的), offering nearly 400 miles of coast, rolling mountains and four distinct seasons. The cost of living is nearly half of what it is in the states at $1,090 and you can find a nice apartment at the reasonable price of $500 per month.PanamaPanama could be a good option for anyone to live cheaply. The cost of living is under half of what it would cost in the U.S. at $1,040 for one person. Rent runs approximately $530 per month and food takes up another $353, but outside of that costs are minimal. The country has a mild climate and offers world-class beaches.1．Which country has economical healthcare?A．Ecuador.B．Costa Rica.C．Uruguay.D．Panama. 2．What makes Uruguay special?A．Its reasonable rent.B．Its good bargains.C．Its diverse climates.D．Its cheap apartments.3．How much is the cost of living in the United States?A．Close to $1,090.B．Around $750.C．Under $893.D．Above $2,080.At St. Francis High School in La Canada, Calif, there’s something to be said about math teacher Jim Connor.Truth is, Connor can be a bit of a drudge. But the 70-year-old Vietnam vet says he’s not here to entertain his students. “It drives me crazy when people say school should be fun,” he says. “I mean, it’s nice if it could be, but you can’t make school fun.”And for years, the kids thought that’s all there was to him — until last November, when senior Pat McGoldrick learned they didn’t know the half of him.Pat was in charge of a student blood drive and had just come to Children’s Hospital Los Angeles for a meeting. And he says it was weird: whenever he told someone he went to St. Francis High School, they all said, “Oh, you must know Jim Connor. Isn’t he wonderful? ”“It was disbelief, really,” Pat says. “It was almost kind of finding this alter ego (另一面) that he has.” Inside the blood donor center, Pat found a plaque listing all the top blood donors at the hospital, including the record holder, Jim Connor. Then he learned something even more unbelievable: that whenever Connor isn’t torturing kids with calculus (微积分), he’s on a whole other tangent-cuddling sick babies. Three days a week for the past 20 years, Jim has volunteered at the hospital, stepping in become involved in an activity when parents can’t, to hold, feed and comfort their children.“They tend to calm for him,” Nurse Erin says. “They tend to relax with him. They fall asleep with him.”“I just like them and relate to them somehow,” Connor says.Connor has never been married; he has no kids of his own. But he has fallen hard for these babies.“I’ve always respected him, but now it’s to an even different degree — really to the point where I try to emulate him,” Pat says. “He’s the epitome of a man of service.”4．What do we learn from paragraph 2?A．School can never be fun.B．Connor is highly demanding.C．Connor’s students drive him crazy.D．Connor thinks education is for all.5．What did Pat find out about Mr Connor?A．Mr Connor donated blood as well as his time.B．Mr Connor was awarded for his love toward babies.C．Mr Connor used to be a very strict teacher.D．Mr Connor had a unique teaching philosophy.6．Which of the following is true about Mr. Connor?A．He works two shifts every day for a living.B．He has his alter ego in the eyes of his students all the time.C．He has the ability to connect with those kids he holds.D．He falls hard for those sick kids so he decided not to have his own.7．Which expression can best replace the underlined word “epitome”?A．the best example B．the simplest oneC．the better man D．another candidateA new study found people growing up in rural areas have better navigation (导航) skills than those raised in cities and that people whose home cities have grid layouts (网格布局) are slightly better at navigating similarly organised streets, despite having poorer performance overall.The study involved nearly 4,000,000 participants from 38 countries who played Sea Hero Quest (SHQ), a game requiring them to navigate a boat in a virtual environment to find the places marked on a map. The researchers found that where people grew up influenced their performance in the game, while their present living place did not affect their scores.The researchers compared the home cities of the participants by analysing the “lack-of-order” state of the street networks, to measure the complexity of the layouts. People whose hometown’s street layouts were more ordered like New York were worse at playing SHQ. Those from cities with less ordered street layouts like Prague performed only slightly worse than those from rural areas. To test if people from cities could more effectively find the right direction in environments similar to where they grew up, the researchers developed a city-themed version of SHQ, called CHQ, requiring participants to drive down the streets in a virtual environment from simple grids to more winding street layouts. People growing up in cities with grid layouts were slightly better at navigating in similar environments, although the difference was not as significant as their performance in SHQ.The SHQ project was designed to aid Alzheimer’s research. Professor MichaelHornberger said, “Lack of spatial (空间的) navigation is a key Alzheimer’s symptom in the early stages of the disease. We are seeking to use the knowledge learned from SHQ to develop better disease monitoring tools.” Dr Susan Kohlhaas also said, “Thanks to the amazing response, we have been able to collect data from over four million players. If we’re to understand Alzheimer’s, it’s vital that we have participation from as many people as possible with diverse backgrounds and experiences.”8．What is the finding of the study?A．Street patterns in games are vital to one’s performance.B．People raised in cities have a good sense of direction.C．Growing up in rural areas improves navigation skills.D．One’s present living place affects their navigation skills.9．What did the participants do in the game?A．They drew their own maps of places in a virtual environment.B．They carried out a task of finding the marked place.C．They marked some places on a map to navigate a boat.D．They played games against each other to mark the map.10．What can be inferred about SHQ from Paragraph 3?A．It’s harder than CHQ for those from cities.B．Researchers developed it based on CHQ.C．It evaluates navigation skills better than CHQ.D．Players from New York did better than those from Prague.11．Why does Dr Susan Kohlhaas acknowledge the project?A．It helps Alzheimer’s patients play SHQ.B．It helps people gain navigation skills.C．It helps get a better knowledge of Alzheimer’s.D．It helps spot Alzheimer’s at an early stage.On Feb. 23, an environmental advocacy group “Grassroots” led by students hosted its monthly clothing exchange. The clothing exchange is a free activity on campus where students can donate clothes in exchange for new ones.“One of the key things about sustainability (可持续性) is to reuse,” Crystal Tynon, Co-president and Clothing Exchange Chair, said. “Instead of throwing away old clothes andbuying new clothes, you can donate them and give them a new purpose. You might be done with those clothing items, but someone else might not be.”According to Tynon, “Grassroots” is hoping to expand the activities to other schools. In order to do so, the team is brainstorming new ways to get the word out about donations, hours and events. Now, the clothing exchange is one of the club’s most well-known activities. “Throughout the semester when people realize we have these exchanges, they genuinely bring clothes and participate a lot more. So it does make a difference to clothing sustainability and it does create a community where everyone can share their clothes,” she added.As “Grassroots” is an initiative dedicated to sustainability, paper advertisement is not an option. Instead, the center relies mostly on word-of-mouth and e-mail announcements. It is bringing speakers to campus to talk about sustainability and environmental advocacy. It also has partnerships with local organizations such as “the Sunrise Rochester”, working together to have volunteers become more involved in local sustainability.Chloe Mendoza has been a volunteer since her freshman year. Not only does Mendoza appreciate the intended mission of promoting sustainability, but she also thinks the center has transformed into a safe and accepting community space for all students. Those who have come in looking for something practical often end up leaving with an armful of clothing and a heart full of warmth.“My favorite part about working there is that we get to help people find things that they need for free. Just providing a place for students to go where there isn’t pressure to spend money is really important. A lot of students love saving, so it’s something that students can relate and engage with easily, so I think it’s a really easy way to get students more involved in sustainability,” says Mendoza.12．Which of the following best describes Tynon’s feelings about their clothing exchange?A．Impressive.B．Innovative.C．Demanding.D．Rewarding.13．What can we learn about “Grassroots”?A．It relies heavily on paper advertisements.B．It cooperates with local institutions.C．It invites speakers to be volunteers.D．It earns instant fame in the community.14．What does Mendoza think is an additional benefit of the clothing exchange?A．It brings spiritual comfort.B．It widens the circle of friends.C．It reduces academic pressure.D．It gives a sense of achievement. 15．Which of the following could be the best title for the text?A．Saving Up Through Clothing ExchangeB．Engaging Students in “Grassroots” EventsC．Clothing Exchange Is the Only Way for SustainabilityD．Environmental Advocacy — “Grassroots” Catches On二、七选五your social circle and gain life-enriching benefits by becoming friends with someone younger or older than you. Having friends of different ages can greatly improve the quality of your life.Having older friends can change your attitude towards life because they have already gone through the challenges you are facing. They have been young parents, have survived a job loss, and can help you get through these changes in your own life. 17 Then you’ll feel more ready for what’s coming in future stages.When older people make friends with younger people, they get to share their experiences which can be very rewarding. 18 Giving your wisdom and attention makes you feel better. It gives you meaning and is good for your mental health. Having younger friends can also make you feel younger by including new ideas and energy in your life.19 While making new friends may seem frightening, it’s actually easier than you think. You can first think about your acquaintances or coworkers and see if any of them share your values and interests and would make a good friend. Then see if you can make a coffee date. Besides, you can consider joining in a class that your coworker or acquaintance participates in that you think you will enjoy. 20All in all making friends with people not your age can open your eyes to new ideas and new experiences that can be life-changing.A．For human beings, giving is good.B．Where to find friends sharing a common interest?C．Then how can you make intergenerational friends?D．Having friends at your own age is natural, of course.E．What’s more, younger friends can give you some fresh ideas.F．It’s believed that joining in activities like volunteering is also an effective way.G．An older friend also helps you “try on” certain life experiences before you get there.三、完形填空Every year I’d read over 2,000 college applications from students all over the world.It isrecommendations, one23 is always irresistible in a candidate：kindness.The most surprising 24 of kindness I’ve ever 25 came from a student who had excellent scores and a supportive recommendation from his college counselor(顾问).Even with these qualifications,he might not have 26 .But one letter of recommendation caught my eye.It was from a school security 27 .Letters of recommendation are typically written by people like former presidents,celebrities,and Olympic athletes.The security guard wrote that he supported this student’s admission because of his 28 .

吉林省长春市2023-2024学年高二上学期语文期中试卷( 含答案)

吉林省长春市2023-2024学年高二上学期语文期中试卷姓名：__________ 班级：__________考号：__________信息类文本阅读材料一：中国社会学自诞生之日起，就树立了注重社会调查的学术传统。

今天，发展中国特色社会主义社会学，通过社会调查走进大众的日常生活和精神世界，不断加深对“人”的认识和理解，承担起建构中国社会学自主知识体系的责任。

社会调查是连接理论与实践的枢纽环节，也是对社会的基础与本质予以理解的一种方法体系。

首先，社会调查是具象化的。

社会调查扎根于特定的地域和人群，试图理解和把握在具体情景中展现出来的情感、气质、风俗、社会发展进程以及变迁趋势。

其次，社会调查是历史性的。

要对一个特定资料作出有效解释，深入了解那些习以为常却又容易视而不见的背景；就要将材料置于时间维度之下，社会调查是整合性的。

人类社会发展既存在一般规律，也充斥着碎片化、非预期和非理性现象，做到对事实本身的把握和尊重。

最后，社会调查长于共情。

在具体场景中所唤起的感性认识，可以使事物“活”的一面被充分挖掘出来，由此提炼出的理论便有了直指人心的力量。

中国社会学自诞生之初，就深深打上了社会调查的烙印。

对“人”的理解、现实的观照、理论的创新，这三者的密切结合贯穿学术传统始终。

有学者在民生疾苦中理解社会性质。

陈翰笙的经济调查蕴含人文精神，才能理解乡村社会，并据此判断中国社会的性质，进而找到适合中国的发展道路。

有学者在人的处境中寻找和确立立场。

雷洁琼在江西的经历使她始终秉持“用资料说话”的精神，反对“为了社会学而社会学”，主张着重观察社会变迁给人的发展带来的影响。

有学者用社会调查串联起学科的本土化与国家发展战略。

费孝通所著《江村经济》，也是他后来开展研究的出发点。

改革开放后，费孝通三访江村，探讨了中国式工业化的发展路径，总结出“苏南模式”“温州模式”“珠江模式”等，也体现了改革开放初期国家经济发展战略。

驻足当下，如何应对时代提出的新问题、发展带来的新挑战？回顾我国社会学的发展历程不难发现，将社会调查的实践精神融入历史的、具体的情景之中，使“人”得到认识和尊重，在此基础上建构的社会学自主知识体系，才具有人民性和主体性。
